just picked up a 2ltr type 4 engine for my next bug project (that i dont actually own yet). might be a silly question but will a type 4 lump physically fit into a beetle engine bay? also i have been told its best to use a type 4 2ltr box but again will this work? if not ill just go straight onto a beetle 1500 box. any advise would be appreciate, also any pics or details of anyone who has done it would be cool.
cheers dudes!!! :D

forget the type 4 gearbox, they are hard to find and the bug will need to be irs, a type 4 engine will not fit in a bugs engine bay with its stock cooling, you will need to fit either a porsche style cooling or as i have a dtm style, also you will need to fit a 200 or 210mm flywheel to the engine and fit a spiggot bearing in the flywheel as the beetle box has a shorter input shaft

In order to fit the type 4 engine, you'll need to have the case machined to take a porsche fan housing, buy all the suitable parts and then stick in a unit that, after spending hundreds of pounds on, develops 68 BHP. A 1600 twin port develops 54 BHP in standard form.

Mind you, there is a set of type 4 DCNF carbs on ebay at the moment which would boost the power considerably.

so im guessing this is going to be a lot more hassle than its really worth. considering im trying to build it on a budget. i have been told by someone that has converted their type 4 engine to the porsche fan that it is a horribly pricey option. how much vaguely would the dtm style conversion set me back?

If you want max power then the type 4 is the base motor to have. It can be made to give some serious horsepower. 400 blown bhp or 3.00ltr can be had at a cost. The type 1 engine is not capable of that.

If your fabrication skill are up to it you can use type 1 parts to covert to upright cooling. Things like alternator stands, fibreglass cyclinder shrouds, bolt on pulleys are avaialable to make the task easier, but if you are feeling adventurous the basics are outlined in the Joe Cali conversion manual using stock T1 and T4 parts!

A Type 4 has many advantages over type 1. Case is alu - harder wearing, crank is bomb proof, full flowed filtered oil, greater cooling area etc. However not as cheap to tune as Type 1 as a rule, and heavier (requiring support bar).

I used an easy to source 215mm clutch and installed my T4 motor onto my 1500 beetle gearbox - with a few modifications to the clutch release bearing shaft as below :

You can buy genuine or aftermarket 200mm flywheels that will get you around this problem : though the later release shaft and bearings are more hard-wearing with the added benefit of increased friction/pad area to transmit torque to the wheels.

You do need to put the bearing/bushing into the flywheel as mentioned above as the input shaft is shorter.

The engine we used was a DTM cooled (Joe Locicero era) 2.1 litre unit based on a stock 1800cc with 2l crank, 96mm barrels and pistons etc..total build cost was about 5k UKP : but then we did lots of rude things to it to get serious BHP.! ;)

Debunking Myths

*A type 4 weighs almost the same as a Type 1 when converted to upright cooling (DTM or CSP Type 1 cooling conversion)

* You do not need the overly complex and expensive 911-fan cooling kits to convert a Type 4 to fit in a Bug

* You do not need to take the Type 4 engine apart to convert it

* You can run a Type 4 using your stock Bug/Bus transmission

* A 2 liter Type 4 is MUCH cheaper, even after the conversion than a used 2 liter Type 1

* You can fit a used 2 liter Type 4 for under 1000 pounds, including the cost of the engine itself in many cases

* It is a doddle to convert a Type 4 to work in Type 1 applications.

* A 2 liter Type 4 will put out more than the stock rating 68 hp with twin Dells/Webers and a free-flowing exhaust system. Much more! And more importantly, much more torque. And a camshaft and ported heads should see you past 100 hp.

Anyone who needs help with the conversion is welcome to PM me.

Type 4 into Type 1

I am doing this at the moment - as Jinx will tell you :) To be honest it is actually quite good fun. I am on a budget so no DTM or Porsche shroud. I must get some pictures done. If at any time you need to you can always put in a T1 and put it on hold.

You may be interested in going down the Joe Cali conversion route (Google him : he produces a conversion guide / manual)

You use stock tinware from a type4 and a Beetle engine and sort of hybridise them together.

Theres a technical thread or two in these forums somewhere.

Racing in off road championships in France and Britain, Kingfisher's 1600 Chenowth constantly wiped the floor with type 4 opposition.

My mate Ian's 1914 panel van ran constant 17.8 second quarters over ten years ago.
And it towed the trailer home with a beetle on it.

Saying that, I used to do thousands of miles of recoveries with a 1700 type 4.

Paul Hamilton is one of those people who puts stuff back into the VW scene. Excellent bloke!

I have cut the tinware at the moment and have cleaned up my T1 bits. Just sorting out the engine bay tinware and the the fan shroud in conjunction with the carbs and bits. Its easy to work on as I have a Bieber and at the moment can lift the body off around the engine bay. Just been sorting my engine bay sealing rubbers out tonight. It will be on the back burner for a moment as I need to do the wiring for the car. Then I am going to "pinch" the engine from my other bug as I need to go for the MOT sooner rather than later.

my 2litre to go in my oval. exhaust now cut and welded and all polished, new pulley wheel, then gonna start throwing the gearbox together.

got 40 dells on it, and an a1 type4 into bug exhaust. running a csp upright cooling kit, which is a fibreglass version of the cali cooling kit.

it was cheaper than building a reliable 2 litre type 1 i think as mostly stock type 4.
